Fix #112: Update CLX sources of 2021-09-19 and support inet sockets
Grabbed sharplispers/clx commit 392421d057d62fd7ac9f813405d55937df2f676b and copied all files to our clx directory. Also includes a fix for #112 (closed) so clx can connect with inet sockets, which was fixed in https://github.com/sharplispers/clx/issues/187.
Manually tested using the ssh test case mentioned #112 (closed) and no errors are seen.
